Overview
The RM-2S10 is a compact and versatile 1U rack-mount unit that provides high-quality loudspeaker monitoring and accurate metering for up to twenty analogue and digital stereo audio sources. This can be expanded further with optional expansion cards. The unit accepts a variety of formats and sample rates, making it suitable for professional audio applications.
The RM-2S10 features 10 separate inputs for both analogue and digital sources, with the option for balanced or unbalanced connections. A front panel rotary encoder allows for easy selection of sources, with LED indicators displaying the current selection and signal presence. The unit also includes a pair of line-level audio outputs, configurable as analogue or AES/EBU digital, and a pair of bright 53-segment bargraph meters with seven different scale options. Additional features such as phase meter, audio modifiers, and remote access are also available. The unit can be further expanded with optional HD video input cards for monitoring embedded audio in HD-SDI or SD-SDI signals.

About the Sonifex Reference Monitor
The RM-2S10 is a 1U rack-mount unit offering quality loudspeaker monitoring and accurate, high-resolution metering of up to twenty both analogue and digital stereo audio sources and more with the addition of optional expansion cards. Sources may be in any mixture of analogue and AES/EBU digital formats, with sample rates up to 192kHz accepted.The RM-2S10 has 10 separate analogue and digital inputs. Analogue inputs can be balanced or unbalanced in any combination. The digital inputs have switchable AES/EBU termination for (close-range) bridging operation and there is extra global input gain available for both analogue and digital low-level sources.
Sources (and additional banks of sources, if fitted) are selected via a front panel rotary encoder, with clear LED indication of the current selection. On the RM-2S10, the Source LEDs also act as signal present indicators. A pair of line-level audio outputs, configurable as analogue or AES/EBU digital, follow the selected source at either a fixed level or one mirroring the loudspeaker volume.
The level of the chosen source is displayed on a pair of bright, multicoloured 53-segment bargraph meters, with a choice of seven accurately modelled scales/responses to suit different applications and local preferences. Clear scale labels are provided for you to chose the scale displayed and the meter brightness can be adjusted from the front panel. A separate phase meter indicates channel correlation or phase error conditions. On the rear panel, open-collector alarm outputs provide hardware indication of sustained underlevel, overlevel, phase errors and digital source lock.Six illuminated pushbuttons provide access to a range of audio ‘modifiers’ – instant dimming of the volume, individual muting of each audio channel, stereo-to-mono conversion, phase inversion and Middle+Side transcoding. On the rear panel, logic-level inputs allow direct remote access to the DIM and MUTE functions.
The three-way loudspeaker system is fed via a DSP-based active crossover and a trio of highly efficient Class-D amplifiers. Careful attention to driver selection, materials and case design, plus active DSP equalisation, has ensured a flat response and outstanding reproduction from such a shallow unit. A protective limiter prevents damage to the loudspeakers under overload conditions and the front-panel headphone socket automatically mutes the internal loudspeakers when a plug is inserted. A Balance control allows you to alter the stereo imaging of the left and right channels.
A further five-band parametric equaliser can be accessed for room-equalisation purposes via Sonifex SCi Windows-based remote control software. Source selection, status monitoring and unit ID functions, plus firmware updates to add extra functionality, are all accessible remotely via both USB and RS232 connections in conjunction with Sonifex SCi software. The open control protocol also allows operation with terminal programs or customised applications.Optional additions to the RM-2S10 include HD video input expansion cards, allowing multiple AES groups embedded within an HD-SDI or SD-SDI signal to be de-embedded and monitored, either with (RM-HD1E1) or without (RM-HD1) Dolby® E or Dolby® Digital encoding.
The RM-2S10 unit operates from global mains voltages (85-264V AC, 47-63Hz) without adjustment.
